This is my new over under styl air cannon. it has a 41"*3" air tank and a 37"*2" barrle. I tested it out at 40psi i plan to take it up to 80 today. At 40 psi it did farly well. it shot like 100-150ft over my trees from like 150 ft away. Im hopeing at 80psi it will go like 2 times as far.

I don't see one unrated part...

I actually like this cannon, especially because it uses pressure rated fittings. Most people who build ball valve cannons will just use non-pressure rated ones. A longer barrel would increase power a lot more.
